Thanks for your many suggestions.

Even though my camera claims to provide 30 fps, I suspect that it is 
actually providing 10 fps. I made some attempt to measure the frame
rate, but I was unsuccessful:

entrans --progress-fps -- --raw v4l2src queue-size=16 \
  ! video/x-raw-yuv,width=352 ! queue ! dam \
  ! ffmpegcolorspace ! xvimagesink

SystemError: error return without exception set
<<<< Now reached PLAYING state >>>>
SystemError: error return without exception set

I tried many variations on that theme. What is the proper way to 
diagnose such problems?
